Sorry dont have a parts book handy.. but blown fuses usally means a big part with a heatsink behind it has shorted.

call a wholesale electronics parts house close to you and they might have it or can cross it to a stronger generic.

Polaroid TLX-1911C LCD TV with no picture (black screen) and sound. Which board do I replace? Power supply or Main board?


I would first check the power supply. Check the main fuse, if is blown and there was no power surge from an external source, the supply board has some serious problem. If the fuse is fine measure the output voltage of the power supply board. Check for any swollen electrolytic capacitors, they are the number one cause of every LCD failure I have come across. I just fixed a Polaroid FLM1514 which has a 2956C Ver 2.0 power board driven by a Fairchild CM0765. Turns out the VCC capacitor was bad and not even swollen, sowpped it for a 47uF 50V and presto.

Polaroid model 3211tlxb sept. 2007.ec18 on the power board gets very hot and tv shuts down. i have replaced ec18 and q16 no help


Hi mrdink010,


I've checked my service manual collection but I don't have the copy on this model. I've also search it online and to my links of the service manual but I can't find one to view the schematic diagram of your unit.
The power supply gone to excessive heat due to over current flowing on its circuitry. This is caused by faulty parts like the transistor, IC's, diode, resistor, capacitors, transformer on its line that in most cases have a partial leak. This is hard to diagnose and needs the skills of an expert to determine which part gone bad. Usually this is not caused by one parts only but most of the time multiple parts gone to malfunction.

I would advice you to replaced the entire power supply board rather than troubleshoot this kind of symptoms because it will cost almost the same. Click this LINK(http://www.shopjimmy.com/polaroid-860-az0-mlt666amh-power-supply.htm) for the replacement. Double check the actual part no. of your board that is printed on the white sticker on the board itself before ordering online.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Where is the fuse in a 3701 LCD Polaroid TV/Monitor


In the Polaroid FLH-3701, the fuse is located on the power supply board, next to the AC power connector. It is a small black cylinder. It is labelled F1. Value is 5 amp, 250 volts.
A fuse does not blow for no reason. Most commonly a fuse will fail because of a short someplace on the board. I have this same TV. The fuse blew. The reason was transistor Q6 had shorted. There are two identical paired transistors on the output side. Q6 and Q7. They are both Infineon 11N60C3 MOSFET transistors. Check those for a short. There may be a burnt smell.
More commonly, this TV will fail because of bad capacitors on the power supply board.

TV will not turn on. Went dead shortly after turning on can't get it to turn on again. Seems like it is not getting AC. Yes its plugged in and there is juice to the socket.


If the red ring in front of tv is not lit when it is plugged in it is probably the power pcb. I just ordered one from searspartsdirect.com part # 860-AZO-IPOS150H FOR $45 plus shipping. installed today and everything is fine.

Replacement of fuses on Philips 37PF7320A 37 in. HDTV-Ready LCD


Is the fuse in the plug okay?

If the fuses are not blowing when you are turning the tv on, this suggests that the PSU primary side is okay.

Since you have opened the TV up, I would suggest probing around with a multimeter however I do not want to let you harm yourself or the TV.

Look for any:
